I've just setup BBB 0.80 and integrated is with Moodle 2.4.1+. I'm able to create an activity but when I visit the activity it stuck at "Logging in as moderator ..." It's the same when I switch student: "Logging in as student ..."

The Moodle server has been running fine for years. The BBB server appears to be working correctly at least as far as the demos go. And since I'm able to create a BBB activity, I assume the configuration (URL and salt) is correct also.

Does anyone have any ideas what the problem might be? Or maybe what to check and how to debug?
